In this study, we developed a simple system that could control both temperature and humidity of a general office, when we could use snow stored until summer as a cold heat source of an air-conditioner. In this report, we adopted a most simple analytical model of all air, central control and variable air volume type air-conditioner which had a blower and a single duct in order to investigate the basic characteristics, and we examined temperature and humidity analytically. As a result, the temperature of the air conditioner area could be achieved 17°C of air at the entrance and 27°C at the exit which temperatures were purposed in this analysis. However, the mean humidity of 60% could not be achieved under lower fresh air humidity than 55%, and the mean humidity became the near to the humidity of fresh air. Because this snow air-conditioning system has excellent controllable characteristics and succeeds a filter effect at the snow surface, we can hold expectation to spread this system in a snowy district widely.","PeriodicalId":199097,"journal":{"name":"Journal of Snow Engineering of Japan","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129163500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, a slip accident at tunnel mouth frequently occurs in winter and causes serious danger for human life and a heavy traffic jam. A Horizontal U-Tube (HUT) road heating system was introduced in order to prevent traffic accidents associated with a road freezing at the west side mouth of Nanaori-Toge tunnel, Aizu-bange, Fukushima Prefecture in Japan. A group of Horizontal U-tubes were buried at a depth of 1.2 m in the ground of the central part of the tunnel. The ground heat extracted by the HUT is injected into the anti-freezing pavement blocks made of concrete at the tunnel mouth through a heat injection pipe mounted in each block. Extensive field experiments have been carried out to investigate the pavement surface temperature, extracted ground heat and micro-meteorological characteristics inside and outside the tunnel. This paper presents the field experimental results at Nanaori-Toge tunnel regarding road anti-freezing and ground heat extraction performance of the HUT system. Even when air temperature was 4 °C lower than the freezing point, the anti-freezing pavement connected with the HUT could keep positive. It is concluded that the HUT road heating system using shallow ground heat in the tunnel is effective in preventing the road surface freezing at tunnel mouth.","PeriodicalId":199097,"journal":{"name":"Journal of Snow Engineering of Japan","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131148853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is because a continuous footing is selected for foundations, and embedment depth is made larger than frost penetration depth to increase the resistance to frost heave. In this study, a freeing survey was conducted on the ground in various buildings housing livestock, and a method for preventing frost heave that allows a simplified structure was proposed. Survey results revealed that the freezing environment inside the livestock building was harsher than that outside. It was also found that the inside freezing environment changed with changing building usage. The study results show the freezing characteristics under each condition and the relationship between freezing index and frost penetration depth. A method is proposed for selecting a construction method for livestock buildings that prevents frost heave.","PeriodicalId":199097,"journal":{"name":"Journal of Snow Engineering of Japan","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127616371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
